ABSTRACT:
A method is presented including selecting an initial beam width. The method also includes determining whether a value per frame is changing. A beam width is dynamically adjusted. The method further decides a speech input with the dynamically adjusted beam width. Also, a device is presented including a processor (420). A speech recognition component (610) is connected to the processor (420). A memory (410) is connected to the processor (420). The speech recognition component (610) dynamically adjusts a beam width to decode a speech input.
